Abstract

905,386. Welding by pressure. TUNG-SOL ELECTRIC Inc. Oct. 14, 1959, No. 34835/59. Class 83 (4). [Also in Group XXXVI] In forming an hermetically-sealed enclosure by joining an annular lip 16 of a cover 14 to a base 2 having a minimum width greater than the outside diameter of the cover, the base 2 is provided with a cylindrical wall 6, a metal ring is positioned on the base to engage a surface of the wall, the free end of the wall is flared over the ring to form an annular lip and the lip is cold-pressure welded to the annular lip 16 of the cover member, the ring being locked to the base by forcing the two lips together against the ring as an anvil. A copper or aluminium base 2 on which an electrical component, e.g. a transistor 4 is mounted, is provided with a cylindrical wall 6, Fig. 2, and a steel ring 8 is slid over the wall. The transistor leads are welded to rods 10 fused through the base. The upper end of the wall is flared to form a lip 12 and this lip and the lip 16 of a copper or aluminium cover 14 are pressed together against the ring to form a cold weld and lock the ring in place. Alternatively, a ring 8<SP>1</SP>, Fig. 6, may be fitted within the wall, the wall is flared inwardly to form a lip 12<SP>1</SP> and this lip and lip 16 of the cover are cold-welded as before. The leads may be sealed through the cover.
